Two programs on the lives and accomplishments of social activists Frank and Josephine Duveneck are scheduled Thursday evening in Los Altos.

The Los Altos History Museum has extended its hours to 7:30 p.m. so that visitors can experience the exhibition “Touching Lives: The Duvenecks of Hidden Villa” before screening two videos on the Duvenecks across the way at Bus Barn Theater. The videos – “Memories of Josephine and Frank” and “The Duvenecks of Hidden Villa” – are scheduled to be screened 7:30 p.m. at Bus Barn, 97 Hillview Ave.

Admission to the museum and screenings is free. Light refreshments will be served at the museum.

“Memories of Josephine and Frank” is a new 40-minute video featuring people whose lives the Duvenecks touched. It also includes personal remembrances of the Duvenecks from family members and friends.

The second video, “The Duvenecks of Hidden Villa,” offers additional insight into life at Hidden Villa, the sprawling property the family owned in Los Altos Hills that is now an educational farm and wilderness preserve. The video features interviews with Frank Duveneck and several examples of children enjoying Hidden Villa’s summer camp.
